I'll go a step further (agreeing with you) and say that this is not negative toward Josh at all. It captures all the great things about him, while pointing out where he needs further development. We all know he is not yet a finished product, and occasionally, does not recognize what the defense is doing. Warner is right.
He is smart, hard working and humble. All signs point to him taking the next steps in this process and becoming (he's close now) elite.
